Abstract:
A system modifies data generating haptic feedback to account for changes in user perception of haptic feedback. The system identifies haptic data and determines an estimated amplitude of haptic feedback corresponding to a portion of the haptic data. Responsive to the estimated amplitude of the haptic feedback corresponding to the portion of the haptic data exceeding a threshold value, a refractory period is determined that will occur after haptic feedback corresponding to the portion of the haptic data is applied to the user. The portion of the haptic data is provided to an input interface, and a set of haptic data associated with times within a duration of the refractory period from the identified haptic data is removed to form an adjusted data set that is provided to the input interface to provide haptic feedback to the user in accordance with adjusted haptic data set.
